From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Pectin Methylesterase, a Regulator of Pollen Tube Growth [PDF]
Abstract The apical wall of growing pollen tubes must be strong enough to withstand the internal turgor pressure, but plastic enough to allow the incorporation of new membrane and cell wall material to support polarized tip growth. These essential rheological properties appear to be controlled by pectins, which constitute the principal ...

Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...

The Arabidopsis GPI-anchored protein COBL11 is necessary for regulating pollen tube integrity
Summary: Pollen tube integrity is required for achieving double fertilization in angiosperms. The rapid alkalinization factor4/19-ANXUR1/2-Buddha’s paper seal 1/2 (RALF4/19-ANX1/2-BUPS1/2)-complex-mediated signaling pathway is critical to maintain pollen

Fast Pollen Tube Growth in Conospermum Species [PDF]
An unusual form of pollen tube growth was observed for several Conospermum species (family Proteaceae). The rate of pollen tube growth, the number of tubes to emerge and the ultrastructure of these tubes are given here.Pollen was germinated in vitro in different sucrose concentrations and in the presence of calcium channel blockers, and tube emergence ...

Petrocosmea wentsaii sp. nov. (Gesneriaceae) from Guizhou, China
Petrocosmea wentsaii M.Q. Han, Miao.M. Wang & Yan Liu, a new species from Guizhou, China, is described and illustrated. Petrocosmea wentsaii was found on damp walls in a huge limestone cave. It is most similar to Petrocosmea hexiensis S.Z. Zhang & Z.Y. Liu in the conformation of the corolla.

Hydrodynamics, cell wall and ion dynamics are all important properties that regulate pollen tube growth. Currently, the two main pollen tube growth models, the cell wall model and the hydrodynamic model do not appear to be reconcilable.

A compartmental model analysis of integrative and self-regulatory ion dynamics in pollen tube growth. [PDF]
Sexual reproduction in higher plants relies upon the polarised growth of pollen tubes. The growth-site at the pollen tube tip responds to signalling processes to successfully steer the tube to an ovule.

Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Reproductive abnormalities in interspecific crosses involving Gossypium hirsutum and Gossypium arboreum [PDF]
A successful cross fertilization involving two different species implies that a chain of reproductive process takes placeunhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent andmatching gene ...
